Background

Comfort is a constant goal in the development of human society, and physical comfort is closely related to the clothing worn. The clothes are intermediaries for people to contact with the environment, namely the second skin of human beings, and the research on the comfort of the clothes is more and more emphasized with the progress of the society. The influencing factors of the comfort of the garment are multidimensional and complex. Among them, protecting the human body from being too cold or too hot is a basic requirement for the comfort of the garment and is also a key point for the study of the serviceability of the garment. This is because the thermal and wet comfort most directly affects the physical and mental conditions of the human body, and the heat exchange between the external environment and the body can be prevented when the human body cannot be adjusted by the wearer in the case of over-cooling or over-heating. Therefore, from the point of heat and humidity comfort, the clothes can create a comfortable and convenient microclimate environment for human bodies, so that the heat and humidity test of the clothes is particularly important.

At present, devices which are already used for testing the heat and humidity of clothes cloth comprise a warming dummy, a sweating dummy, a temperature changing dummy and a temperature adjusting dummy. The warm-up dummy is mainly used for evaluating the non-evaporative heat dissipation performance of the clothes, namely testing the thermal resistance of the clothes, but the non-evaporative heat dissipation performance cannot reflect the heat and humidity performance of the clothes, the evaporative heat dissipation is caused by human body sweating, and the sweating dummy is required to be used for measuring the moisture permeability index of the clothes. The temperature-changing dummy controls the temperature of the dummy according to the temperature-changing rule between the heat dissipation capacity of different parts of a human body and the local skin temperature. The thermoregulation dummy is then a more advanced intelligent simulation. However, the above devices are complicated in structure and implementation, and are expensive.
